==Introduction==
The shape and size of the skull varies widely, not only between species but also with age, breed and sex of similar species. The skull is divided into three components- the neurocranium, the dermatocranium and the viscerocranium. The skull also includes the [[Hyoid Apparatus - Anatomy & Physiology|hyoid apparatus]], mandible, ossicles of the middle [[Ear - Anatomy & Physiology|ear]] and the cartilage of the [[Larynx - Anatomy & Physiology|larynx]], nose and [[Ear - Anatomy & Physiology|ear]]. The skull protects the brain and head against injury and supports the structures of the face. In some animals the skull is also used for defensive actions, for example in [[Horn - Anatomy & Physiology|horned]] ungulates such as red deer stags.
